IMPROVEMENT IN KING-BOLTS FOR CARRIAGES.

Specification forming part of Letters Patent No. 136,255, dated February25, 1873.

To all whom it may concern:

Be it known that I, JOHN L. H. MOSIER, of the city, county, and State ofNew York, have invented a new and useful Improvement in King-Bolt forPlatform Carriages, of which the following is a specification:

Figure 1 is a top view of a portion of a carriage illustrating myinvention. Fig. 2 is' a dctail section of the same, taken through theline 50 a, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of king-bolts for platform-carriages so as to make them neat, strong, anddurable, and, at the same time, give a smooth finish to the top plate ofthe front bed of the top carriage. head formed upon the king-bolt, andthe corresponding recess formed in the top plate of the front bed of thetop carriage, said crosshead and recess being so formed as to correspondand leave the upper surface of the cross-head flush with the uppersurface of the said top plate, giving a smooth finish; and in the bolts,in combination with the cross-head of the king-bolt and with the topplate, the bed, and the bottom plate of the top carriage, as hereinafterfully described.

A is the front bed of the top carriage. B is the top plate of the frontbed A. C is the bottom plate of the front bed A. D is the kin gbolt,which passes down through a hole in the top plate B, front bed A, andbottom plate 0. Upon the upper end of the king-bolt D is formed across-head, d, which is made to correspond with the shape of the topplate B, and

The invention consists in the crossf is let into a recess formed in theupper side of the middle part of the top plate B, which recess is madeof such a depth that the upper surface of the head d may be finishedflush with the surface of the top plate B, thus giving aperfectly-smooth finish to the upper side of said top plate. E are twobolts, which pass through the end parts of the cross-head d oftheking-bolt D, through'th'e top plate B, the bed A, and bottom plate 0;and their heads are countersunk into the said cross-head, so as to beflush with its upper surface. The bolts E are secured in place by nutsscrewed upon their lower ends. Upon the lower side of the bottom plateC, around the hole through which the king-bolt D passes, is formed asocket, C, sufficiently large to receive the thimble formed upon thefrog F, and through which the king-bolt D passes, as shown in Fig. 2.Upon the lower end of the king-bolt D is screwed a nut, G, which issecured in place and kept from working 011' by a small transverse bolt,H, passing through a hole in the said nut G and in the said bolt D, andwhich is secured in place by a small nut screwed upon its forward end.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- The combination with the bed A of the curvedcross-headedking-bolt D d,recessed top plate B, bottom plate C, andbolts E E, as and for the purpose described.
